Subject: [PATCH AUTOSEL 4.14 172/371] NFS: Don't interrupt file writeout due to fatal errors
Date: Thu, 16 Jan 2020 12:20:44 -0500
Message-ID: <20200116172403.18149-115-sashal@kernel.org> (raw)
In-Reply-To: <20200116172403.18149-1-sashal@kernel.org>

From: Trond Myklebust <trondmy@gmail.com>

[ Upstream commit 14bebe3c90b326d2a0df78aed5e9de090c71d878 ]

When flushing out dirty pages, the fact that we may hit fatal errors
is not a reason to stop writeback. Those errors are reported through
fsync(), not through the flush mechanism.

Fixes: a6598813a4c5b ("NFS: Don't write back further requests if there...")
